対応する適合面上に支持される。DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a holder with a recess, a blade insert, particularly compatible for metal machining, with a blade insert inserted into said recess and fixed therein by a retaining screw. The tool relates to a tool in which the implanter has a recess for the implanter, the implanter is supported on a seating surface of the implanter and is in contact with at least two mating surfaces, and wherein the implanter is provided with a recess for the implanter, the implanter being supported on the seating surface of the implanter and in contact with at least two mating surfaces, The retaining recess has a planar bottom surface and a generally semi-cylindrical support surface extending perpendicularly from the bottom surface on its side remote from the effective cutting point. is supported on a corresponding matching surface of the
一般にタングステンカーバイド製の互換性植刃の場合、
有効刃先から離れた側部において植刃が最も巾広の表面
でホルダに支持されることが重要である。Generally, for interchangeable blades made of tungsten carbide,
It is important that the implant is supported by the holder with its widest surface on the side remote from the effective cutting edge.
このためホルダまたはホルダに挿入された植刃台上に相
互に成る角度をなして延びる少くとも2つの支持面をも
つ 各隅角が90°よりやや小さい角をもつしばしば用
いられるような六角形植刃の場合、もしこれらの植刃が
2つの支持面で支持されたとすれば回転および寸法的に
正確な取付けを保証することが望まれる。For this purpose, a hexagonal implant, as is often used, with at least two support surfaces extending at an angle to each other on the holder or on the implant bed inserted into the holder, each corner having an angle of slightly less than 90°, is used. In the case of blades, it is desirable to ensure rotationally and dimensionally correct mounting if these blades are supported on two support surfaces.
一方においてホルダに対して寸法的に正確に植刃を固定
するため、また他方において機械加工中に発生された力
を植刃から確実にホルダに伝達し、同時に不使用の刃先
に損傷を与えないために、植刃を完全に支持することが
非常に重要なことである。On the one hand, to fix the cutting edge dimensionally accurately in the holder, and on the other hand, to reliably transmit the forces generated during machining from the cutting edge to the holder, without damaging the unused cutting edge. Therefore, it is very important to fully support the implant.
植刃の外郭形状に対応して相互に成る角をもって形成さ
れるばかりでなく、支持表面に対する植刃の形状によっ
て決められる角度と正確に一致した角度をもたなければ
ならないこれらの支持面を製作することは、必然的に高
価な特殊機械工具を必要とする。These support surfaces must not only be formed with mutually intersecting angles corresponding to the contour of the implant, but also have an angle that exactly corresponds to the angle determined by the shape of the implant relative to the support surface. Doing so necessarily requires expensive special mechanical tools.
複雑な工具の場合支持面の製作はその場所が小さく、か
つ植刃を寸法的に正しく位置決めする指標がないので困
難となる。In the case of complex tools, the production of support surfaces is difficult due to the small space and lack of indicators for dimensionally correct positioning of the implant.
正面バイトの使用者は、しばしば旋削工具ホルダ、穿孔
工具ホルダ、穿孔ヘッドその他特殊工具のような実用的
な工具ホルダを自分で作って使用し、これらのホルダに
別の工場製の植刃を固定する方法をよく用いる。Users of front-facing tools often use their own practical tool holders, such as turning tool holders, drilling tool holders, drilling heads, and other special tools, to which they fix other factory-made inserts. I often use this method.
しかし、このことは従来支持面を製作することが困難な
ためにほとんど不可能であった。However, this has heretofore been almost impossible due to the difficulties in manufacturing the support surfaces.
植刃がホルダに直接取付けられずホルダに挿入可能な植
刃台に取付けられたような上述型式の工具が知られてい
ることは事実である。It is true that tools of the above-mentioned type are known in which the inserting blade is not attached directly to the holder, but to a inserting stand which can be inserted into the holder.
該植刃台は植刃用の正確に機械加工された支持面をもつ
。The implanter has a precisely machined support surface for the implanter.
しかしその外形は植刃台の挿入に必要な凹部をホルダに
設けるのに凹部の加工が簡単であるようなものである必
要がある。However, its external shape must be such that the recess necessary for inserting the blade implantation table can be easily machined to provide the recess in the holder.
既知の植刃台はほぼU形外郭をもつ。The known implantation table has an approximately U-shaped profile.
半円筒形支持面によって2つの互に平行な横向き面が合
体結合される。Two mutually parallel transverse surfaces are joined together by a semi-cylindrical support surface.
植刃台はその下側に平担な底面をもつ。The cutting table has a flat bottom on its lower side.
エンドミル切削具を用いて前記植刃台を受入れる凹部を
比較的容易にホルダに設けることができる。A recess for receiving the blade implantation base can be relatively easily provided in the holder using an end mill cutting tool.
しかしこの既知の植刃台はその外形寸法が植刃に比して
太き過ぎるので多くの場合使用できない。However, this known blade implantation stand cannot be used in many cases because its external dimensions are too thick compared to the implantation blade.
これは主として前端を植刃上に支持され後端を植刃台で
支持された締付爪によって植刃台上に支持されていると
いう事実に帰せられる。This is mainly attributable to the fact that it is supported on the implantation table by a clamping pawl whose front end is supported on the implantation blade and whose rear end is supported on the implantation table.
該締付爪および締付爪を保持する締付ねじを収容するた
めに、植刃台は必然的に大型に製作しなげればならない
。In order to accommodate the clamping pawl and the clamping screw that holds the clamping pawl, the blade implantation stand must necessarily be manufactured in a large size.
その外側寸法のために、既知の植刃台もまた比較的大型
の凹部を備える必要があり従って可成りホルダを弱める
ことになる。Due to their external dimensions, known implantation stands also have to be provided with relatively large recesses, thus weakening the holder considerably.
この理由からもこの既知の植刃台は使用される頻度は少
ない。For this reason as well, this known implantation stand is rarely used.
他の工具がまた米国特許第2630725号明細書によ
って知られており、この場合植刃台の平面形はほぼ矩形
である。Another tool is also known from US Pat. No. 2,630,725, in which the planar shape of the implantation table is approximately rectangular.
植刃は植刃の中央孔に挿入された締付爪によってこの矩
形の一隅に固定される。The implant blade is fixed to one corner of this rectangle by a tightening claw inserted into the center hole of the implant blade.
対角線上で向合った隅の区域に、植刃台は保持ねじをね
じ込むねじ孔を具え、該ねじによってホルダに固定され
る。In the area of diagonally opposite corners, the implantation table is provided with a screw hole into which a retaining screw is screwed, by means of which it is fixed to the holder.
この既知の植刃台もまた比較的大きい余地を必要とし、
そのうえホルダ内に収容されるのに要する矩形凹部が製
作困難であるという不利点をもつ。This known implantation table also requires a relatively large amount of room;
Moreover, it has the disadvantage that the rectangular recess required to be accommodated in the holder is difficult to manufacture.
本発明の目的は植刃台が可能な限り小型で、かつこれを
ホルダに取付けるのに必要な凹部が製作簡単な前述型式
の交換可能な多角形植刃を有する工具を提供することで
ある。The object of the invention is to provide a tool with an exchangeable polygonal insert of the type described above, in which the inserter is as small as possible and the recess necessary for mounting it in the holder is simple to manufacture.
上述の目的は本発明によって達成でき、すなわち、植刃
台には締付ねじ用の中央孔が設けられ、植刃台の半円筒
形支持表面の軸線が中央孔の軸線と完全にまたはほぼ合
致し、なお保持ねじ用のねじ孔または孔が植刃の下方で
植刃台に設けられている。The above-mentioned object can be achieved by the present invention, namely, the implantation base is provided with a central hole for the tightening screw, and the axis of the semi-cylindrical support surface of the implantation base is completely or approximately aligned with the axis of the central hole. However, a screw hole or hole for a retaining screw is provided in the implant base below the implant blade.
支持表面の半径は中央孔の軸線から切削点までの距離よ
りもわずかに大きいことが好ましい。Preferably, the radius of the support surface is slightly larger than the distance from the axis of the central hole to the cutting point.
本発明による工具において、植刃台の寸法は特に小型で
ある。In the tool according to the invention, the dimensions of the cutting head are particularly small.
植刃台の切削上部平面は植刃自身よりもごくわずか太き
い。The upper cutting plane of the cutting board is very slightly thicker than the cutting blade itself.
植刃台は植刃の下側において植刃の高さにほぼ相応する
高さをもつ。The height of the blade base on the underside of the blade is approximately equal to the height of the blade.
しかし大部分の工具ではいずれの場合でもホルダと植刃
との間にシム板が設けられるから、本発明による工具の
場合、植刃および植刃台に必要とする場所の大きさはシ
ム板をもつ植刃が必要とする場所の大きさよりもわずか
に太きいだけである。However, in most tools, a shim plate is provided between the holder and the inserting blade in any case, so in the case of the tool according to the present invention, the space required for the inserting blade and the inserting stand is reduced by the shim plate. It is only slightly thicker than the area required for motu-ueba.
このように所要場所が小さいから、植刃台は従来植刃が
ホルダに直接取付けられていた場所にはいずれにも実際
に用いられる。Because of this small space requirement, the implant stand can be used practically anywhere where implant blades have conventionally been attached directly to a holder.
はぼ半円筒形支持表面および平担な底面をもつ植刃台の
外郭形状が単純であるため、ホルダに設げられる凹部は
エンドミルによって極めて簡単に製作できる。Due to the simple outer shape of the implantation table with its semi-cylindrical support surface and flat bottom surface, the recess provided in the holder can be produced very easily with an end mill.
この理由からこの工具の使用者はもし必要ならば彼等自
身で製作できる。For this reason users of this tool can make their own if necessary.
これらのホルダは別の製造者に植刃およびその挿入台を
発注すれば足り、これらは高い精度で適当な特殊機械で
製作され、なおこれらは常に同一形状を有するから特別
の工具とは無関係に多量に製造できる。For these holders, it is sufficient to order the inserting blade and its insertion stand from another manufacturer; these are manufactured with high precision on appropriate special machines, and they always have the same shape, so no special tools are required. Can be manufactured in large quantities.
本発明による工具の特に有用な実施例において、植刃台
は固定用孔をもち線孔は植刃台の底面に対し垂直に延び
、固定ピンが固定用孔および保持用凹部の対応する孔と
係合する。In a particularly useful embodiment of the tool according to the invention, the implanting base has a fixing hole, the wire hole extends perpendicularly to the bottom surface of the implanting base, and a securing pin connects the securing hole and the corresponding hole of the retaining recess. engage.
該固定ピンによって植刃台はホルダに対し正確に固定さ
れ、ホルダに対する植刃台の回転および変位が防止され
る。The fixing pin accurately fixes the implantation table to the holder and prevents rotation and displacement of the implantation table with respect to the holder.
図面を参照しつつ若干の実施例について本発明の詳細説
明を以下に述べる。A detailed description of the invention will now be provided with reference to some embodiments and with reference to the drawings.
図面において1は工具全体をあられし、該工具はホルダ
2、植刃台3およびタングステンカーバイドなどの植刃
4からなる。In the drawings, reference numeral 1 denotes the entire tool, which includes a holder 2, a blade implantation stand 3, and a blade implantation 4 made of tungsten carbide or the like.
植刃台3を受入れるために、ホルダ2には凹部5が設け
られこの中に植刃台3が正確に嵌まる。In order to receive the blade implant 3, the holder 2 is provided with a recess 5 into which the blade implant 3 fits precisely.
植刃台は平担な底部6を具え、かつこの面と垂直なほぼ
半円筒形支持表面7をもつ。The implantation table has a flat bottom 6 and a substantially semi-cylindrical support surface 7 perpendicular to this plane.
このほぼ半円筒形支持表面の円弧範囲はほぼ植刃の形状
に合った形状となっている。The arc range of this approximately semi-cylindrical support surface has a shape that approximately matches the shape of the implant.
第1〜7図に示す六角形植刃、および第9図に示す平行
四辺形の植刃の場合はこの円弧範囲は約135°である
が、第8〜10図に示す矩形または三角形植刃の場合は
約1600である。In the case of the hexagonal blade shown in Figures 1 to 7 and the parallelogram blade shown in Figure 9, this arc range is approximately 135°, but in the case of the rectangular or triangular blade shown in Figures 8 to 10. In the case of , it is about 1600.
ここに用いた「はぼ半円筒形の」という語は、従って約
135°から約160°の範囲の角度にわたるものとす
る。As used herein, the term "roughly semi-cylindrical" is therefore intended to span an angle ranging from about 135 degrees to about 160 degrees.
植刃台3はさらに植刃4を受は入れるための凹部8をも
つ。The implantation stand 3 further has a recess 8 for receiving the implantation blade 4.
この凹部の境界は着座面9および支持面10,11,1
2によってきめられる。The boundary of this recess is the seating surface 9 and the support surfaces 10, 11, 1
Determined by 2.
植刃4はこれらの錆面上で支持される。植刃4は中央孔
13をもち植刃台3のねじ孔15にねじ込まれる締付ね
じ14によって植刃4は植刃台3上に保持される。The implanted blade 4 is supported on these rusted surfaces. The implant blade 4 has a central hole 13, and the implant blade 4 is held on the implant base 3 by a tightening screw 14 screwed into a screw hole 15 of the implant base 3.
図示実施例における半円筒形支持表面7の中心線とねじ
15の軸線Aとは合致もしくはほぼ合致していなげれば
ならない。The center line of the semi-cylindrical support surface 7 and the axis A of the screw 15 in the illustrated embodiment must coincide or substantially coincide.
その全寸法を最小にするためには、もし支持表面7の半
径Rをねじ孔15の軸線から刃先4a、4b。In order to minimize its overall dimensions, if the radius R of the support surface 7 is reduced from the axis of the screw hole 15 to the cutting edge 4a, 4b.
4cへの距離よりも極くわずかだけ大きくすることが一
層有利である。It is even more advantageous to make it only slightly larger than the distance to 4c.
支持表面1が支持されるホルダ2に設けられた適合表面
16は支持表面と同一の半径をもつ。The matching surface 16 provided on the holder 2 on which the support surface 1 is supported has the same radius as the support surface.
両者の良好な接触を確保するためには支持表面7の中央
部分7aの半径がその両側部分7bの半径よりもやや小
さく、これによって植刃台3が、ホルダの四部5の適合
表面16とその両針側範囲のみで接触することが有利で
ある。In order to ensure good contact between the two, the radius of the central part 7a of the support surface 7 is slightly smaller than the radius of its side parts 7b, so that the implantation table 3 is in contact with the mating surface 16 of the four parts 5 of the holder. It is advantageous to contact only in the two needle side areas.
植刃台3をホルダ2へ確実に取付けるために、植刃台2
には下方から挿入される保持ねじ18用のねじ孔17が
設けられる。In order to securely attach the blade planting stand 3 to the holder 2,
is provided with a screw hole 17 for a retaining screw 18 inserted from below.
該ねじ孔17は植刃4の下方に設けられるから植刃台3
は可能な限り小寸法に作ることができる。Since the screw hole 17 is provided below the implantation blade 4, the implantation base 3
can be made as small as possible.
保持ねじ18は植刃台3をホルダ2に恒久的に保持する
から、植刃4を交換したり回転変換したりするときも、
植刃台は常にホルダに対し固定位置を保つ。Since the holding screw 18 permanently holds the implantation table 3 to the holder 2, even when replacing the implantation blade 4 or changing its rotation,
The implant stand always maintains a fixed position relative to the holder.
もし要すれば植刃台に植刃の中央孔と同名の孔を設け、
なおホルダにこの目的のために植刃および植刃台を貫通
する保持ねじをねじ込むための同名のねじ孔を設けるこ
とも考えられる。If necessary, make a hole with the same name as the center hole of the blade on the blade planting table,
It is also conceivable to provide the holder with a screw hole of the same name for screwing in a retaining screw passing through the implant and the implant stand for this purpose.
この場合、−個のねじで植刃と植刃台の両方を固定する
ことができる。In this case, both the blade implant and the blade implant base can be fixed with - number of screws.
植刃台3をホルダ2へ正確に固定するには、固定ピン1
9を備えることが好適である。To accurately fix the implantation table 3 to the holder 2, use the fixing pin 1.
9 is suitable.
該固定ピンを受入れるために植刃台3にその底面6と直
角に延びる固定用孔20を設け、なおホルダ2にこれと
対応する同名の孔21を設ける。In order to receive the fixing pin, a fixing hole 20 extending perpendicularly to the bottom surface 6 of the blade implantation stand 3 is provided, and a corresponding hole 21 with the same name is provided in the holder 2.
ホルダの孔21はまづ保持ねじ18によって植刃台3を
ホルダ2に固定し、次にあらかじめ穿孔された固定用孔
を孔21を穿孔するための穿孔ゲージとして用いて穿設
される。The hole 21 in the holder is first fixed to the holder 2 by the holding screw 18, and then the previously drilled fixing hole is used as a drilling gauge for drilling the hole 21.
植刃台において第1〜6図に示すように、他の刃先がそ
れぞれ90°よりもやや小さい角度をもつ六角形植刃を
受入れるために、固定用孔20は90°よりもやや小さ
い角度をもつ2つの支持面lL12の交点に設けること
が好ましい。As shown in Figures 1 to 6 in the implantation table, in order to accept a hexagonal implantation blade in which the other cutting edges each have an angle slightly smaller than 90°, the fixing hole 20 has an angle slightly smaller than 90°. It is preferable to provide it at the intersection of the two supporting surfaces 1L12.
この場合固定用孔20は同時に支持面lL12間の隅部
に対しては接触しない孔となり刃先4bは露出される。In this case, the fixing hole 20 simultaneously becomes a hole that does not come into contact with the corner between the supporting surfaces 1L12, and the cutting edge 4b is exposed.
固定ピン19を用いることによって、植刃台3は高い圧
力を受けても常に保持具に対しその位置が固定されるか
ら、植刃は常にそのあらかじめ定めた位置を保つ。By using the fixing pin 19, the implantation table 3 is always fixed in its position relative to the holder even when subjected to high pressure, so that the implantation blade always maintains its predetermined position.
もし要すれば、固定ピンをさらに植刃台3′と植刃4′
との微調整用の回転軸として用いることもできる。If necessary, attach the fixing pins to the implantation stand 3' and the implantation blade 4'.
It can also be used as a rotation axis for fine adjustment.
第6図において調整ねじ22を用いて、植刃台31を成
る制限範囲内で固定ピン19′のまわりに調整すること
ができる。In FIG. 6, with the aid of the adjusting screw 22, the implant base 31 can be adjusted around the fixing pin 19' within the limits defined.
この調整はせいぜい1/loimの範囲で生じ、かつ極
めて高精度を要求される場合における取付不良を修正す
るのに用いられるに過ぎないから、もし固定ピンの近傍
の植刃台31が既に適合表面16’に接触していれば、
固定ピン19′の弾性変形によって得られるものである
。This adjustment occurs within the range of 1/loim at most and is only used to correct installation defects in cases where extremely high precision is required. If it is in contact with 16',
This is achieved by elastic deformation of the fixing pin 19'.
この方法で、遊びのない特に正確な調整を得ることがで
きる。In this way, a particularly precise adjustment without play can be obtained.
第1図の植刃台3と第6図の植刃台3′とを比較すると
、いずれの場合も2つの支持面10.11または10’
、11’は有効切削点4aまたは4 a’と反対位置に

本図は該植刃台の全寸法が小型であるために穿孔ヘッド
および特殊正面バイトの場合と全く同じように用いるこ
とができることを単に示すことを意図するだけである。This figure is only intended to show that the overall dimensions of the implantation table are so small that it can be used in exactly the same way as in the case of drilling heads and special front bits.
第8〜10図は矩形、平行四辺形および三角形植刃用の
植刃台を示す。Figures 8 to 10 show blade planting stands for rectangular, parallelogram and triangular blades.
これらの図は本発明が他の多角形植刃にも適用できるこ

う優れた効果を有するものである。In this invention, with the above structure, the recess of the holder only has a flat bottom surface and a semi-cylindrical fitting surface extending perpendicularly to the bottom surface, so that the holder can be accommodated in the recess and the holder. The holder is very easy to process and has low processing costs, and the diameter of the semi-cylindrical support surface of the holder is smaller in the center than on both sides, making it easy to adapt the support surface to the holder. The connection with the surface is ensured, and the grafting table can be firmly fixed to the holder.Furthermore, the grafting table can be fixed to the holder, and the grafting blade can be fixed to the grafting table using screws. , and the outer dimensions of the blade implantation stand are formed to be slightly larger than the external dimensions of the blade implantation, so the blade implantation stand can be made smaller than conventional ones, and therefore the blade implantation of the holder can be made smaller. This has the excellent effect that the recess for accommodating the stand can be made small and there is no risk of damaging the strength of the holder.
